At Advanced Bariatrics, Our Patients Say it Best…
JOEL U. (Age: 41)
I find myself wanting to go to
the gym 4-5 times per week!
Dr. Cheregi helped me to see that this procedure was merely the start of a new way of life for me. Since the surgery, my health has continued to improve both physically and mentally. I can feel it in my knees and back especially and find myself no longer needing to take breaks from strenuous activity.
ADINA B. (Age: 3o)
This surgery gave me my confidence back along with my health.
Losing 175 pounds in a little less than a year really puts things into perspective. I am a new woman and a better person… A huge thank you Dr. Chang for giving me the chance at a rewarding, healthy, and fulfilling life. I’m living the life I always wanted to and that is the best feeling in the world!
COLIN C. (Age: 34)
This surgery was and still is
absolutely life changing!
The impact the surgery has had on my life is nothing short of amazing! I look and feel so much better… it’s basically given me my life back! I never thought in a million years, I would be wearing a size 32 pants and a small or medium shirt. I am fortunate that my wife and I were able to go on this journey together.
